摘要： The present invention relates to an orthopedic plate and screw system and instruments for surgical fixation of a small bone or bones. The plate facilitates three dimensional contouring to provide for a variety of applications and to accommodate individual variation in bone shape. The plate has a modified x shape including a central trunk portion including one or more screw holes along a longitudinal axis and a set of divergent upper and an oppositely extending set of divergent lower arms, each arm including screw holes which are placed at a radially equal distance but which diverging asymmetrically from the longitudinal axis relative to its paired upper or lower mate. The screws of the system are self-starting, self-tapping screws including the option of partial or full cannulation.

摘要： A surgical drill guide for positioning, aligning, and of holes to be drilled in bone tissue has retaining means that holds the position and alignment of the drill guide body in a releasable manner with respect to a fastener hole in an orthopedic implant. The retaining means is a key guide that mates with a key way or key ways in or around a threaded locking hole of an orthopedic plate for alignment of a pilot hole and method of using the guide. The key guide has 2 to projections that extend in the direction of the axis of the hole, such as hemi cylindrical projections, and the plate has a corresponding female key way that receives the retaining means. The invention also relates to a method of aligning a locking fastener in a plate at a desired angle relative to a bone by using a surgical guide having a key interface with the plate to position and align a pilot hole.

摘要： The present invention relates to an orthopedic screw and a corresponding screw driver wherein the screw has a torque driving head with a rounded side a spherical wall for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a cancellous thread. The threaded portion has a major diameter defined by a spiraling thread and a minor diameter. The head is joined to the threaded portion by an area of from about 2 to about 6 turns of the thread along the longitudinal axis in which the minor diameter tapers by an angle of from about 4° to about 12° and the major diameter of the screw remaining substantially the same. The screw includes a multilobe torque driving recess joined to a cylindrical recess that corresponds to a cylindrical post on the torque driver so as to form a press fit which acts to self-center the screw, to help avoid stripping of the screw/driver interface and to hold the screw in place on the torque driver prior to implantation.

摘要： An orthopedic plate system comprises a plurality of fasteners such as pegs or screws and a plate having two sets of holes for the fasteners. The first set of at least one hole includes internal threads that receive a fastener having a head which includes external threads that mate with the internal threads of the hole to lock the fastener at a fixed angle relative to the plate. The second set of at least one hole is devoid of internal threads and has a concavely rounded internal surface and which receives a convexly rounded external surface of a locking insert, which receives a variable axis fastener. The variable axis fastener causes the locking insert to expand to lock the variable axis fastener at a selected angle relative to the plate.

摘要： A drill having a head that has a modified egg shape. The distal most end of the drill head is rounded and has a smaller diameter with a cutting bevel which flares into an area having a maximum diameter that is slightly larger than the diameter of the corresponding screw or implant that is used in the surgical procedure. The distal end of the drill also includes a plurality of cutting flutes which extend part of the way up the narrower portion of the drill head just up to the area having the maximum diameter. This drill can then be used to turn a countersink area into the bone at the implant site.

摘要： A locking mechanism assembly to allow locking of a fastener in an orthopedic implant having its axis at a variable angle relative to the axis of a concavely rounded through opening in the implant. The assembly includes a convexly rounded ring shaped locking cam insert which mates with the through opening and further which includes an expansion slot. The cam insert includes two cam raceways on the inside that are engaged by cam members on the head of the fastener. The cam members increase radially and expand the insert in the through opening to hold it in position by friction. The cam insert further includes a stop member that inhibits the cam insert from rotating as the fastener is rotated in the cam insert and locks it into the desired position.
摘要翻译：一种锁定机构组件，用于允许将紧固件锁定在整形外科植入物中，所述矫形植入物具有相对于所述植入物中的凹入圆形通孔的轴线可变的角度。组件包括与通孔相配合并且进一步包括扩展槽的凸形圆形环形锁定凸轮插入件。凸轮插入件包括在内侧的两个凸轮滚道，凸轮滚道与紧固件的头部上的凸轮构件接合。凸轮部件径向增大并使插入件在通孔中膨胀，以通过摩擦将其保持在适当的位置。凸轮插入件还包括阻止凸轮插入件旋转的止动构件，因为紧固件在凸轮插入件中旋转并将其锁定到期望的位置。

摘要： The present invention relates to an orthopedic screw having a torque driving head with spherical surface for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a modified cancellous thread. The threaded portion has a major diameter defined by a spiraling thread and a minor diameter. The head is joined to the threaded portion by an area of from about 2 to about 6 turns of the thread along the longitudinal axis in which the minor diameter tapers by an angle of from about 4 to about 12° and the major diameter of the screw remaining substantially the same meaning that the major diameter is constant to about +/−0.05 mm along the length of the threaded portion. The screw includes a multilobe torque driving recess joined to a cylindrical recess that corresponds to a cylindrical post on the torque driver so as to form a press fit which acts to self-center the screw, to help avoid stripping of the screw/driver interface and to hold the screw in place on the torque driver prior to implantation. In a further embodiment, the screw includes a variable pitch portion for about half of the length starting from the distil end. The screw can be used be itself, or with a plate. Further a new method of using the screw with a plate is presented in which the screw extends through a cortical section of bone into a cancellous portion but not through the adjacent cortical.
摘要翻译：本发明涉及具有用于多轴使用的具有球面的扭矩驱动头的自动螺丝，自启动，自攻丝插入尖端和包括修改的松质线的螺纹部分。螺纹部分具有由螺旋螺纹和较小直径限定的大直径。头部沿着纵向轴线连接到螺纹部分约2至约6圈的螺纹区域，其中小直径锥度约4至约12度的角度和螺杆的大直径保持与螺纹部分的长度大致相同的意思，即长径大约为+/- 0.05mm。所述螺杆包括多个转矩驱动凹部，所述多叶扭矩驱动凹部接合到对应于所述扭矩驱动器上的圆柱形柱的圆柱形凹部，以便形成用于使所述螺钉自对中心的压配合，以有助于避免螺钉/驱动器接口的剥离，在植入前将螺丝固定在扭矩驱动器上。在另一实施例中，螺杆包括从蒸馏端开始的大约一半长度的可变节距部分。螺钉可以自己使用，也可以用于板材。还提出了使用具有板的螺钉的新方法，其中螺钉通过骨的皮质部分延伸进入松质部分而不通过相邻的皮层。
